javascript - Vimeo API 跟踪

Question

我正在尝试对我们网站上的 Vimeo 视频实现一些视频跟踪。我已经完成了 Play/Finished 任务，但我还需要完成 25%、50%、75%。

这是我当前的代码

$(document).ready(function() {
   	var iframe = document.querySelector('#vimeo_id_0');
   	var player = new Vimeo.Player(iframe);
	
	//Track videos on Play
	player.on('play', function(data){
		player.getVideoTitle().then(function(title) {
			$('body').append('<div>Play:' + title + '</div>');
		});
		//ga('send', 'event', { eventCategory: 'Video', eventAction: 'Play', eventLabel: 'Video Play'});
	});
	
	//Track videos at percent played
	player.on('timeupdate', function(data){
		player.getVideoTitle().then(function(title) {
			console.log(data.percent);
			if(data.percent = 0.25) {
				//25% percent
				$('body').append('<div>25%' + title + '</div>');
			} else if (data.percent = 0.50) {
				//50% percent
				$('body').append('<div>50%' + title + '</div>');
			} else if (data.percent = 0.75) {
				//75% percent
				$('body').append('<div>75%' + title + '</div>');
			}
		});
	});
	
	//Track videos on End
	player.on('ended', function(data){
		player.getVideoTitle().then(function(title) {
		  $('body').append('<div>Ended:' + title + '</div>');
		  //ga('send', 'event', { eventCategory: 'Video', eventAction: 'Finished', eventLabel: 'Video Finished'});
		});
	});
});

<script src="https://player.vimeo.com/api/player.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<style>.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }</style><div class='embed-container'><iframe src='https://player.vimeo.com/video/260024854' id="vimeo_id_0" frameborder='0' webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe></div>

我试图得到它，所以当 timeupdate 百分比达到 0.25 时，它将触发事件，就是这样，但是它会立即开始触发，并在每次 timeupdate 调用更新时触发，这意味着我们将跟踪事件负载在 Google Analytics 中

如有任何帮助，我们将不胜感激。谢谢

在您的 if 语句中，您缺少另一个等号。应该是:

if (data.percent == 0.25)
